Mystery Mountain Winter Park officially opened last week, but the real celebrations will be happening this weekend.

Sandy Little with Mystery Mountain says they will be participating in World Snow Day- a world wide event started by the International Ski Federation 4 years ago. 

Events will include lessons, races, a potluck, and indoor games all day tomorrow.

You can hear more about the event this afternoon at 12:40 and 5:10 during Thompson Today.
